[A principle of maximum topological similarity in molecular systematics]

Abstract

The paper deals with the problem of phylogenetic reconstruction on the basis of comparative analysis of features. Main attention is paid to comparison and classification of the biopolymer sequences. Different approaches to this task are critically reviewed. The novel principle of construction of tree-like classification schemes permitting subsequent evolutionary analysis is proposed. It concentrates on reconstruction of the tree with a topologic structure that is most close to topologic features, imprinted in the source distance matrix. Realization of this approach was made possible by development of the special formalism, enabling evaluation and comparison of topologic features of distance matrices and trees.
